Abstract: PURPOSE:To accelerate a processing and to miniaturize a system by providing a demultiplexing means and a wavelength conversion means, inserting an optical signal not demultiplexed by the demultiplexing means into the output optical signal of a wavelength conversion means and generating an optical signal output subjected to wavelength multiplexing. CONSTITUTION:An N-wavelength multiplexer 2 multiplexes an optical signal having a wavelength corresponding to each channel fed from an N-wavelength demultiplexer 1 and optical signals whose wavelengths are lambdaI-lambdaIV from a wavelength converter 3 to generate an optical signal output subjected to wavelength multiplexing. A control section 4 uses control information extracted from an optical signal whose wavelength is lambdaC demultiplexed from an optical signal input at the demultiplexer 1 to control the converter 3, thereby converts the input optical signal to be inserted in the converter 3 into a prescribed wavelength. The optical signal whose wavelength is lambdaC is the signal of a common wavelength to each node, subjected to wavelength multiplexing together with the optical signal of each channel and sent sequentially to each node and used for the control of wavelength conversion in each node. The processing such as bit synchronization or frame synchronization in this system is not required and the constitution is simplified.

Inventor: WADA MASAMI
IPC: H02M3/155
Filed: 1984-03-09
Abstract: PURPOSE:To eliminate the generation of a noise such as an unnecessary radiation by turning OFF a switching element when a pulsating voltage exceeds a certain voltage to eliminate the transmission of the pulsating voltage to the output side.

Title: Socket for examination
Inventor: SUGANO TSUKASA
IPC: H01L23/32
Filed: 1988-02-29
Abstract: PURPOSE:To carry out the examination work efficiently by packing a liquid conductor in a socket main body. CONSTITUTION:While metallic springs 3a and 3b are arranged in a socket main body 1 penetrating their one end in a base plate 2, a molten low temperature solder liquid 4 is packed in the socket main body 1. As a result, when the lead terminals of a circuit are connected to the springs 3a and 3b in the examination of a mixture integrated circuit, the linking condition between the lead terminals and the springs 3a and 3b is maintained through the low temperature solder liquid 4, even though a dirt and the like are attached to the leads, or the springs 3a and 3b reduce the holding force of the lead terminals, for example. Consequently, the electric connection between the lead terminals and the springs 3a and 3b can be maintained in a good condition constantly, and the examination work can be carried out efficiently.

Title: Taxiway for unmanned carrier
Inventor: IMAMURA YOSHINOBU
IPC: G05D1/02
Filed: 1985-03-08
Abstract: PURPOSE:To guide and travel correctly the unmanned carrier and to facilitate to change the laying even in the curved taxiway by using a light absorber for the taxiway of the unmanned carrier of the optical guiding system. CONSTITUTION:The light irradiated from a floodlight 61 is reflected from a floor surface 4 including a guiding body 5, photodetected and detected by a photodetecting element 62 and signals ON and OFF are emitted. On the other hand, since the guiding body 5 is formed by a light absorber, and the light quantity of the irregular reflecting light LB is small, a facing photodetecting element 62' does not detect this. The irregular reflecting light LF of the floor surface 4 excluding the guiding body 5 is scattered at the circumference. Since the floodlight is a line light source, the light LF is detected by the photodetecting element 62 except the element 62'. Since the irregular reflecting light is LF>LB, respective elements 62 are detected as ON and the element 62' is detected as OFF, and detected as assembling signals of the binarization signal of ON and OFF based on the layout of respective photodetecting elements. Consequently, when the elements overshoot from a taxiway 5, the assembling is different, and a steering signal is emitted based on the assembling stipulated by a microcomputer beforehand.
